Carnival Upheaval is the fourth level of Angry Birds Rio. It has a moving background. You can collect the golden papayas along the way. The Pigs return in this theme, this time in the form of balloons. The last level of Carnival Upheaval is a boss fight with Mauro.

The end cutscene shows a single panel of Blu launching himself to the allegoric car with the rare species caged again. The other panels show Blu finding Jewel until Nigel captures him in the allegoric car, which the Birds follow to the airfield.
